HEELING-MACHINE.

Specification of Letters Patent.

Patented Aug. 26, 1919.

- Application filed November 4, 1915, Serial No. 59,530. Renewed January 6, 1919. Serial No. 269,970.

To all whom it may concern:

Be it known that I, Fnnonnrox A. EMERY, a citizen of the United States, residing at l-laverhill, in the county of Essex and State of Massachusetts, have invented an Improvement in Heeling-Machines, of which the following is a specification.

This invention relates to certain improve-- ments in heeling machines, and more par ticularly to machines for attaching heels which comprise a leather base-section, and a rubber top-section, through each of which the attaching-nails must be driven.

At the present time, the rubber top-sections are attached both by hand and by machine, and, while they may be attached by machine somewhat more rapidly than by hand, the machines which are, so far as I am aware, at present in use, for this purpose, rc-

quire great :physical exertion, on the part of the operator, for the reason that the attaching-nails must be driven about l; of an inch below the level of the tread surface of the rubber heel section, and, to do this, the operator has to jack the heel, by means of the foot-treadle, against the nail plate with sufficient force to compress the rubber to a considerable extent before the final pressure of the machine is applied thereto, so that the nails will be driven into the base-section to such an extent that, when the rubber expands the nails will be countersunk, to some extent, although, usually, not to the extent desired.

The object of my invention is to provide a machine, of the above-described character, with means whereby the leather base section may be easily and rapidly attached, and the attaching-nails of the rubber top-section may be driven and countersunk to the desired extent, and the whole operation may be performed without greater diiliculty or ef fort on the part of the operator than is necessary in attaching an ordinary leather heel and top-lift.

I accomplish this object by the means shown in the accompanying drawings, in which an embodiment ofmy invention is shown, and in which Figure 1 is a front elevation of a wellknown form of heeling-machine provided with certain parts embodying my invention.

The main portion of the machine, to which I have shown my invention as applied, is of similar construction to the machine illustrated in the U. S. patent to Pope, #446,885, said machine comprising a main frame 10, having a main driving shaft 11, mounted therein, said shaft bein arranged to reciprocate the cross-heat 12, mounted on the vertical side rods 13. The jack 14 is mounted beneath the cross head upon an adjustable support 15, which is adapted to be raised by a treadle 16, through intermediate mechanism, comprising a rack bar 17 arranged to rotate a gear 18, mounted on an elevating screw 19, on the upper end of which the support 15 is carried, so thatthe jack will be raised when theitreadle is depressed, and lowered when the pressure on the treadle is removed, a spring 9 being provided to lift the same, and to operate the parts actuated thereby 1n the opposite direction. The machine thus far described is wellknown in the art, and is believed to require no further description.

'According to my invention, a cross bar 8 is rigidly supported on the-machine frame in such a position that the side rods 13 pass through the ends thereof, and a bracket plate 20 is supported on said bar in a horizontally disposed position. A nail-platecarrier 22 is provided, which comprises a flat, circular, metal casting, of suitable thickness, rotatably mounted on and sup- .ported by a bolt 23, beneath the plate 20.

The rear side of the cross bar 8 is cut away to provide a segmental shaped recess, extending from top 'tobottom thereof, 1.0 receive the front portion of the carrier, as shown in Figs. 3 and 4. Adjustable stop bolts 24, 25, are provided on said carrierfin position to engage the bar 8 and limit the movement 'ofrotation thereof to 90- from either extreme position. Said carrier 22 is r said recesses, any suitable means for 'locking them in position belng priovidedxrA driver block 7 28 is removably mounted on the "under side of the cross head,12 and said nail plates 26,27 are so arrangedin 'the carrier22 that'one or the other will be 1helddirectly' beneath said driver block inv one orthe other of the extreme positions of the carrier, shown in Figs. 3- and 4., Two distinct gangs of drivers 29 and; 30, are mounted in said driverjblock, the driver 39 gang 29 being shown as depending a short distance below the ends of the drlver'gang '30. -t The driver blocks 26, 27, are each pro- 'vide d with two sets of nail passages 29 and -30? (see Fig. .13), which correspond exactly 3 5 arrangement and size tothe drivers offthe :two gangs-29 and 30, -respe.ctively,1sothat, when the cross head is-lowered, said drivers -will;pass into and-through the correspond- 'ing passages of the particular driver block- A O which is at that time in "position beneath the drivers.

With the abovedescribed construction, .when carrier 22 min such av posltionthat thenail plate 26 :is heldbeneath thedriver block 28,- so that the drivers wouldpass through. thenailpassagesof said plate, and is, therefore, in its nailing position, the other plate 27 will be held in a position 190 therefrom at the left sideof the machine,

: e0 while, when the plate 27 is held in its nail-.

ling-position, the plate 26 will be in the di- ',-rectly opposite position at the right side of the machine. The bracket plate .20 isso formed that it does not extend beneaththe driver block and=isrecessed from its edge directly over the'twordiametrically opposite positions. of nailplates26, 27, at the right and left of the machine, above referred to.

Nail-sticking plates 31, 32, are removably mounted on the plate '20 directly over these recesses, the plate 31 having apertures 30" therein, corresponding in position to the apertures 30 -in the nail plates 26, 2 7, and

the plate32 having apertures 29. therein,

'6 corresponding 'in position to the apertures therebetween.

29 of said nail plates. Said plates 31 and 32'are also supported in such positions that V the apertures thereof will register with the corresponding apertures of the nail plates when the latter are held thereunder. I

'i The carrier 22 is provided with, heelholding means on its under side, in position to hold a heelblank directly beneath and against the under side of the nail-plates 26 and 27. The particular construction of heel holding means, which Ipreferably employ to :hold the. blank beneath the nail plate 27, is particularly shown in Figs. 5', 9, 10, and 14-,1and is mounted inapair of parallel ribs 39 on the under side ofthe carrier 22, said ribs having a pair of guideways formed inatheir adjacent'sides, one; over the other (see Fig. 10).. A pair of:

parallel arms 38 are mounted to-slide in the uppermost of said guide-ways, the outer ends of said arms being connected by a heelbreastengag1ng bar 38, and an intermediate portion thereof being connected by a cross-. bar 42. A plate 37 having aV-shaped heel- "receiving and centering recess in one end thereof, .is mounted to slide inthe lowermost ofsaid guide-ways, 'saidlplate being connected by paralleharms, or rods 37, to'. a cross plate 37 tothe 'rear'end' of which 21 depending rib 40 issecur'ed', an adjusting screw 4-1, having a swivel connection with the carrier 22, being threaded in said: ribA-O,

whereby the position of said plate 37 may 7 be adjusted. Said'cross bar as .and plate 27 are connected by springs 43, which act to draw the bar 38 toward the heel-receiving endof; the plate 37 By. this arrangement,

the position ofa. heel-blank held between the bar 38 and plate 37 maybe varied with relation to the. nail plate :27 without varying the force with which'the springs 43 draw the bar 38' against a heel held in the recess vide a concaverecess, to correspond to the '.of plate 37 The means for supporting a rubber top-section-beneath the-nail plate 26 comprises a rib 35 which is attached to the under sideo-f plate '26, and is formed toprorear portion of the heel-blank, and a breast 1 engaging bar 36 which is mountedon dowels 35, in the rib 35, to move transversely toward, and from the recess of the latter, and springs 44 are arranged to draw said bar toward said plate, to clamp the blank rotated onits pivot 23.

To operate the machine to its: greatest capacity, the operator einploys'two assist- The carrier 22 has handles 45thereon, so that it may be conveniently ants, who stand at the right and left sides of'the machine, and stick the nails and place the heel blanks in the'holder. The operator of the'machine stands in front of the mach'ine in the usual manner,and places the shoe Orr-the jack. indicated in Fig. 2. blank m, for the heel base, is placed between;

the members 37 and 38, while they are in the position beneath the loading plate 31, and a nail is placed in each hole of the plate 31, so that it will pass into the corresponding nail passages in the nail plate 27 and rest on the blank, as shown in Fig. 10.

The nail plate carrier 22 is then rotated through 90, in the direction of the arrow in Fig. 3,. carrying the nail plate 27, with the heel blank supported therebeneath, into position over the jack and beneath the driver block. The operator then depresses the treadle 16 and lifts the jaclg'forcing the heel seat of the shoe thereon firmly against the heel blank in the desired position of attachment, the position of the blank being adjusted, if necessary, by the screw l1, and then he operates the starting mechanism of the machine, so that the cross head 12is causedto descend, and the driver gang 30 to enter the passages 30 and engage the nails thereon, and drive them through the blank into the heel seat, in the ordinary way, so that the blankis attached thereto. The relative arrangement is such that the drivers 30 are carried down to the level of the under side ofthe nail plate, so that the nails will be driven flush with the surface of the heel. The drivers 29 will, at the same time, pass into and through the passages 29, and, as these drivers are somewhat longer than the drivers 30, their ends will be carried below the surface of the plate'and be forced into the top portion of the heel blank, so that they will prick a corresponding series of holes therein, to a depth corresponding to the distance which they project below the ends of the drivers 30, as shown inFigs. 5 and 7'.

While the carrier is in the position to attach the heel base, shown in Fig. 4, the operators assistant places a rubber top-section 3 between the clamp members 35 and 36 and then sticks-a nail into each hole 29 of the plate 32, so that these nails rest on said heel section, as shown in Fig. 11. As

soon as the cross head is lifted, the carrier is then rotated in the opposite direction, as indicated by the arrow in Fig. 4, returning it to the position of Fig. 3, and bringing the rubber top-section into position over the base-section'which has just been attached. When the cross head moves up, the operatorreleases the treadle 16, so that the jack is lowered, and, as soon as the top section is moved into position over the jack, he again depresses the treadle'16 and presses the heel base, which has just been attached, up against the under surface of thetop sec tion, and, while the parts are held in this Tpostion, the machine is again operated, so

- that the cross head again descends, and

causes the longer drivers 29 to engage the nails which have been placed in the nail passages 29. and. to drive them into and through the rubber heel and into the heel base, so that the rubber section will be attached thereto. As, in the previous operation, the base section has been pricked to some extent by the longer drivers 29, these prick holes will assist in the proper guidance ofthe attaching nails of the top-section, when they emerge from the latter and pass into the heel base, said prick holes being, obviously, in exact alinement with the direction in which these nails are driven, and between the nails which have been driven into the heel base, so that the attaching nails of the top section will not encounter those of the base-section.

As has been stated, it is necessary that the attaching nails of the rubber top section be countersunk to the depth of about i: of an inch the extent to which the drivers 29 extend below the surface of the nail plate, when the cross head is in its lowest position, is made to correspond to this distance, so that thenails, driven thereby, will be driven below the tread face of the top section to a corresponding extent, as shown in Figs. 6 and 8. As the drivers 30 are not moved below a point where their ends are flush with the surface of the nail plate, it follows that, while the longer drivers 29 will drive the nails below the tread face of the rubber top, the drivers 30 only will touch its surface, and will not penetrate the same, so as to cause injury thereto.

The cross head then ascends again, and, as the attaching operation is then finished, the shoe may be removed, and the operation repeated. The operation of attaching the leather heel base and rubber top section may thus be rapidly and effectively performed, the operation being as rapid and easy for the operator as the ordinary operation of attaching the ordinary heel and top lift.

The above described devices, constituting an embodiment of my invention, may be easily applied to the well-known commercial machine above referred to, without modification, other than the substitution of these devices for certain other devices with which such machines are usually provided.

It will be obvious that the nail plates, nail-sticking plates, and driver blocks, will be changed according to required conditions, and that, while the rotatably mounted nail-plate carrier is more desirable than any other construction of which I am aware, it is not essential to the generic principles of my invention. Also, that. while I prefer to have the carrier rotated through about 'i of a revolution in each direction, so that two operators assistants maybe employed to advantage, and the are, through which the carrier is oscillated, may be as short as practicable, thereby enabling the volume of work performed to be increased to the greatestextent, practicable, yetif asingle assistant is to be vemployed, it would be quite as desirable to have the carrier moved as near 7 to a revolution as wouldbe possible,with out, having the two sets of naihsticking passages interfere. with each other, and have the assistant'stationed in the rear of the machine'to which; position the nailplates would then be carried forloading It will also beunderstood'thatautomatic j nail-loading means may be employed for each of the nail plates, instead of having 7 the nailsinserted by hand. 1

By having both gangs oji-driverson one block and both nail plates provided with nail passages" for each gang, the speed of the machine is considerably increased over anar-v rangement in which the drivergangs would be mounted inseparate driver blocks on a turret, carried by the head, and successively brought into position over the jack, in the well-known manner in which separate gangs of 'awlsyand drivers have been previously employed; for the reason that the time re parent that it would be posslble to employ quired to change the turret after each nailing operation would cause additional delay.

ItWil-l'be understood, however, that my in vention is not limited to the arrangement of both driver gangs on'the same head, but that this is a greatly preferred and highly advantageous construction, not only for the reason that the speed of the machine is--in creased, but also becausethe advantage due to thepricking of thebase section to receive the top sectionnails'." It will be .furtherap only one nail plate-in attachinglooth base and top sections of the heel, by first placing the baseesection-blank 'in position beneath the nail plate, and driving the attaching nails from one set of nail passages and then placing the top-section-blank in .posltion beneath the same-nail plate, andrdrivingth'e attaching nails therefor from the other set of nail passages. While this operation would be substantially slower than that al-V ready described, as the preferred method'of operation, yet the advantage of having one 7 set of drivers longer than the other .set, s0 that the base section would be pricked and the top section attaching nails would' be countersunk, would stillbe secured.
